Replacement British Leyland Headed Key RV An exact re-creation of the vintage ignition key that came as original equipment with so many of our British sports cars. Compare your key with that shown by mousing over lower image to see other images. Cross-sections show view looking from tip of key towards the head. Keys are sent as blanks and can be cut to fit your car at any local key shop for a nominal charge. Check to make sure your blank key fits into ignition before cutting. Note. Over the last few years replacement ignition lock assemblies from suppliers have come with a key that looks very similar to this one - however the key is thicker than the original. At present we do not have a replacement key for the non-original replacement locks. Application - most MGB 1977-1980 that still have original ignition locks.
